' This invention relates to improvements draft riggings especially adapted for mine cars.

Y One object of the invention is to provide adraft rigging of simple design, which maybeA economi# cally manufactured and-which is adapted tofsuccessfully fcushionY lbotlr the draft and bufing shocks to which mine cars are subjected in service.

'A' more specific object of the inventionaisfto provide a draft riggingof the character specified '101 in the preceding paragraph comprising ajminimumnumber of parts by utilizing the cushioning means which isused to absorb the buffing shocks to also absorb-the draft shocks, and employing' a single member in the vform of a; transverse beam having Vbufling headsv atV opposite ends thereof and a coupler connection intermediate A-its' ends to transmit the bufring cushioning' means. j

A still further object of the invention isyto pro- '20' vide in a draft rigging for mine -cars means for absorbing both draft and buffing shocks, wherein the draft and buffing strains are distributed through the car structureY by vsupporting the shock absorbing means on the side sills `of the n 25 car andfimparting both the bufing and draft forces thereto by means of ar single member having buing heads at opposite ends'thereofand'a draft connection centrally between the ends. j

Other objects of the invention will more clearly 30. appear from the description'and vclaims herein after following. ,A In the drawings, forming a part' of thisv specif` v:(cation,V Figuie1 is a part plan andpartjliorizontal sectional view of a mine car, illustrating my improvements in connection therewith; the horizontal section beingtaken through theunder-V frame structureof the car. rvFigure 2is1alo ng'i# tudinal, vertical, sectional view, corresponding substantially to the line 2-2 of Figure 1.

From'the preceding description taken in ,connection with the drawings, it will be seen that I have provided a simple and eflicientlshock absorbing means for mine cars, which is effective Ainbcth bu and draft, wherein the structure isy of simple and economical design, a transverse vbeam/.memberat each end of the car being employed to transmit bothy the draft and bulng shocks to the shock absorbing mechanisms. A further advantage of my improved design` is that a minimum amount of space is occupied by theshockl absorbing mechanism, the same being placed between the pairs of longitudinal sill members which are located at opposite sides of the mine car underframe.

I have herein shown and described what I now consider the preferred manner ofvcarrying out my invention, but the 4same is merely illustrative and I contemplate all changes and modifications that come within.v the scope of the claims ap-v pended hereto.
